Intuit closed Mint and pointed 13 million people at Credit Karma. If you kept the CSV export, Budgetfold reads it as is and rebuilds your accounts and categories. If you moved to Monarch or YNAB since, those export too.
Budgetfold is $39 a year because it does not. There are no offers, no credit-score upsell and no bank connection to maintain. What you get is the envelope method Mint never had: money is assigned before it is spent, not categorised after.
